We
wrote the year 1977 when Texas Instruments introduced with the TI-1700 DATACLIP
a calculator shaped like a ruler. Within one year both Canon and Toshiba
responded with the Ruler-8 resp. this
LC-850M.
Dismantling
the Toshiba LC-850M reveals a standard design based on the Toshiba T3567
single-chip calculator circuit introduced together with its sibbling T3566
located in the TI-1790 Datachron.
